You have given 2 array. You need to find whether they will
create the same BST or not.
For example:
Array1:10 5 20 15 30
Array2:10 20 15 30 5
Result: True
Array1:10 5 20 15 30
Array2:10 15 20 30 5
Result: False
One Approach is Pretty Clear by creating BST O(nlogn) then
checking two tree for identical O(N) overall O(nlogn) ..we
need there exist O(N) Time & O(1) Space also without extra
space .Algorithm ??

if(n1!=n2) return false;
//n1 and n2 must be same
for(i=0;i<n1-1;i++)
{
if( !( (a1[i]>a1[i+1]) && (a2[i]>a2[i+1]) )

return true;//assumed that each array doesn't contain
duplicate elements in themshelves
